The tangent ratio is a trigonometric function that measures the ratio of the length of the opposite side to the length of the adjacent side in a right triangle. It is abbreviated as tan. The tangent ratio is often used in surveying, navigation, and other applications where angles and distances need to be measured.

The tangent ratio can be calculated using the following formula:tan() = opposite / adjacentwhere is the angle between the opposite and adjacent sides.

The table below shows the tangent ratios for some common angles:| Angle () | Tangent (tan()) ||—|—|| 0 | 0 || 30 | 1/3 0.577 || 45 | 1 || 60 | 3 1.732 || 90 | undefined |

The tangent ratio is a useful tool for solving problems involving right triangles. For example, it can be used to find the height of a building or the distance to a star.
